Аннотация

The medicinal plant Thermopsis optimal conditions for obtaining cellulose and microcrystalline cellulose from (meal and stem), from which active substances were first isolated, were determined using acid and alkaline cooking methods. Microcrystalline cellulose was synthesized from the obtained cellulose by hydrolysis. Cellulose hydrolysis was carried out in a mixture of sulfuric acid and hydrogen peroxide in a ratio of 8:2. The ash content of cellulose and microcrystalline cellulose samples was determined in a muffle furnace, the degree of water absorption in a centrifuge, moisture absorption in a desiccator, the content of easily and poorly soluble substances in the stem content in a photocolorimeter, and physical and chemical indicators such as bulk density and moisture were determined. Key words: medicinal plant, cellulose, meal, microcrystalline cellulose, ash content, cooking module, alkali, acid.
